Abstract

We report new and precise measurements of the decay branching fractions of the lepton to one and three charged particles. The data, corresponding to an integrated luminosity of 176 pb-1, were collected by the high resolution spectrometer HRS at the e+e- storage ring PEP at SLAC operated at s=29 GeV. The fractions of decays into one and three charged particles are 0.8690.0020.003 and 0.1300.0020.003, respectively.
